FIELD OF THE INVENTION

The present invention involves DNA mismatch repair genes. In particular, the invention relates to identification of mutations and polymorphisms in DNA mismatch repair genes, to identification and characterization of DNA mismatch-repair-defective tumors, and to detection of genetic susceptibility to cancer.

BACKGROUND

In recent years, with the development of powerful cloning and amplification techniques such as the polymerase chain reaction (PCR), in combination with a rapidly accumulating body of information concerning the structure and location of numerous human genes and markers, it has become practical and advisable to collect and analyze samples of DNA or RNA from individuals who are members of families which are identified as exhibiting a high frequency of certain genetically transmitted disorders. For example, screening procedures are routinely used to screen for genes involved in sickle cell anemia, cystic fibrosis, fragile X chromosome syndrome and multiple sclerosis. For some types of disorders, early diagnosis can greatly improve the person's long-term prognosis by, for example, adopting an aggressive diagnostic routine, and/or by making life style changes if appropriate to either prevent or prepare for an anticipated problem.

Once a particular human gene mutation is identified and linked to a disease, development of screening procedures to identify high-risk individuals can be relatively straight forward. For example, after the structure and abnormal phenotypic role of the mutant gene are understood, it is possible to design primers for use in PCR to obtain amplified quantities of the gene from individuals for testing. However, initial discovery of a mutant gene, i.e., its structure, location and linkage with a known inherited health problem, requires substantial experimental effort and creative research strategies.

One approach to discovering the role of a mutant gene in causing a disease begins with clinical studies on individuals who are in families which exhibit a high frequency of the disease. In these studies, the approximate location of the disease-causing locus is determined indirectly by searching for a chromosome marker which tends to segregate with the locus. A principal limitation of this approach is that, although the approximate genomic location of the gene can be determined, it does not generally allow actual isolation or sequencing of the gene. For example, Lindblom et al.³ reported results of linkage analysis studies performed with SSLP (simple sequence length polymorphism) markers on individuals from a family known to exhibit a high incidence of hereditary non-polyposis colon cancer (HNPCC). Lindblom et al. found a "tight linkage" between a polymorphic marker on the short arm of human chromosome 3 (3p21-23) and a disease locus apparently responsible for increasing an individual's risk of developing colon cancer. Even though 3p21-23 is a fairly specific location relative to the entire genome, it represents a huge DNA region relative to the probable size of the mutant gene. The mutant gene could be separated from the markers identifying the locus by millions of bases. At best, such linkage studies have only limited utility for screening purposes because in order to predict one person's risk, genetic analysis must be performed with tightly linked genetic markers on a number of related individuals in the family. It is often impossible to obtain such information, particularly if affected family members are deceased. Also, informative markers may not exist in the family under analysis. Without knowing the gene's structure, it is not possible to sample, amplify, sequence and determine directly whether an individual carries the mutant gene.

Another approach to discovering a disease-causing mutant gene begins with design and trial of PCR primers, based on known information about the disease, for example, theories for disease state mechanisms, related protein structures and finction, possible analogous genes in humans or other species, etc. The objective is to isolate and sequence candidate normal genes which are believed to sometimes occur in mutant forms rendering an individual disease prone. This approach is highly dependent on how much is known about the disease at the molecular level, and on the investigator's ability to construct strategies and methods for finding candidate genes. Association of a mutation in a candidate gene with a disease must ultimately be demonstrated by performing tests on members of a family which exhibits a high incidence of the disease. The most direct and definitive way to confirm such linkage in family studies is to use PCR primers which are designed to amplify portions of the candidate gene in samples collected from the family members. The amplified gene products are then sequenced and compared to the normal gene structure for the purpose of finding and characterizing mutations. A given mutation is ultimately implicated by showing that affected individuals have it while unaffected individuals do not, and that the mutation causes a change in protein function which is not simply a polymorphism.

Another way to show a high probability of linkage between a candidate gene mutation and disease is by determining the chromosome location of the gene, then comparing the gene's map location to known regions of disease-linked loci such as the one identified by Lindblom et al. Coincident map location of a candidate gene in the region of a previously identified disease-linked locus may strongly implicate an association between a mutation in the candidate gene and the disease.

There are other ways to show that mutations in a gene candidate may be linked to the disease. For example, artificially produced mutant forms of the gene can be introduced into animals. Incidence of the disease in animals carrying the mutant gene can then be compared to animals with the normal genotype. Significantly elevated incidence of disease in animals with the mutant genotype, relative to animals with the wild-type gene, may support the theory that mutations in the candidate gene are sometimes responsible for occurrence of the disease.

One type of disease which has recently received much attention because of the discovery of disease-linked gene mutations is Hereditary Nonpolyposis Colon Cancer (HNPCC).¹,2. Members of HNPCC families also display increased susceptibility to other cancers including endometrial, ovarian, gastric and breast. Approximately 10% of colorectal cancers are believed to be HNPCC. Tumors from HNPCC patients display an unusual genetic defect in which short, repeated DNA sequences, such as the dinucleotide repeat sequences found in human chromosomal DNA ("microsatellite DNA"), appear to be unstable. This genomic instability of short, repeated DNA sequences, sometimes called the "RER+" phenotype, is also observed in a significant proportion of a wide variety of sporadic tumors, suggesting that many sporadic tumors may have acquired mutations that are similar (or identical) to mutations that are inherited in HNPCC.

Genetic linkage studies have identified two HNPCC loci thought to account for as much as 90% of HNPCC. The loci map to human chromosome 2pl5-16 (2p21) and 3p21-23. Subsequent studies have identified human DNA mismatch repair gene hMSH2 as being the gene on chromosome 2p21, in which mutations account for a significant fraction of HNPCC cancers.¹, 2, 12 hMSH2 is one of several genes whose normal function is to identify and correct DNA mispairs including those that follow each round of chromosome replication.

The best defined mismatch repair pathway is the E.coli MutHLS pathway that promotes a long-patch (approximately 3 Kb) excision repair reaction which is dependent on the mutH, mutL, mutS and mutU (uvrD) gene products. The MutHLS pathway appears to be the most active mismatch repair pathway in E.coli and is known to both increase the fidelity of DNA replication and to act on recombination intermediates containing mispaired bases. The system has been reconstituted in vitro, and requires the MutH, mutL, MutS and uvrD (helicase II) proteins along with DNA polymerase III holoenzyme, DNA ligase, single-stranded DNA binding protein (SSB) and one of the single-stranded DNA exonucleases, Exo I, Exo VII or RecJ. hMSH2 is homologous to the bacterial MutS gene. A similar pathway in yeast includes the yeast MSH2 gene and two mutL-like genes referred to as PMS1 and MLH1.

With the knowledge that mutations in a human mutS type gene (hMSH2) sometimes cause cancer, and the discovery that HNPCC tumors exhibit microsatellite DNA instability, interest in other DNA mismatch repair genes and gene products, and their possible roles in HNPCC and/or other cancers, has intensified. It is estimated that as many as 1 in 200 individuals carry a mutation in either the hMSH2 gene or other related genes which encode for other proteins in the same DNA mismatch repair pathway.

An important objective of our work has been to identify human genes which are useful for screening and identifying individuals who are at elevated risk of developing cancer. Other objects are: to determine the sequences of exons and flanking intron structures in such genes; to use the structural information to design testing procedures for the purpose of finding and characterizing mutations which result in an absence of or defect in a gene product which confers cancer susceptibility; and to distinguish such mutations from "harmless" polymorphic variations. Another object is to use the structural information relating to exon and flanking intron sequences of a cancer-linked gene, to diagnose tumor types and prescribe appropriate therapy. Another object is to use the structural information relating to a cancer-linked gene to identify other related candidate human genes for study.

SUMMARY OF THE INVENTION

Based on our knowledge of DNA mismatch repair mechanisms in bacteria and yeast including conservation of mismatch repair genes, we reasoned that human DNA mismatch repair homologs should exist, and that mutations in such homologs affecting protein function, would be likely to cause genetic instability, possibly leading to an increased risk of developing certain forms of human cancer.

We have isolated and sequenced two human genes, hPMS1 and hMLH1 each of which encodes for a protein involved in DNA mismatch repair. hPMS1 and hMLH1 are homologous to mutL genes found in E.coli. Our studies strongly support an association between mutations in DNA mismatch repair genes and susceptibility to HNPCC. Thus, DNA mismatch repair gene sequence information of the present invention, namely, cDNA and genomic structures relating to hMLH1 and hPMS1, make possible a number of useful methods relating to cancer risk determination and diagnosis. The invention also encompasses a large number of nucleotide and protein structures which are useful in such methods.

We mapped the location of hMLH1 to human chromosome 3p21-23. This is a region of the human genome that, based upon family studies, harbors a locus that predisposes individuals to HNPCC. Additionally, we have found a mutation in a conserved region of the hMLH1 cDNA in HNPCC-affected individuals from a Swedish family. The mutation is not found in unaffected individuals from the same family, nor is it a simple polymorphism. We have also found that a homologous mutation in yeast results in a defective DNA mismatch repair protein. We have also found a frameshift mutation in hMLH1 of affected individuals from an English family. Our discovery of a cancer-linked mutations in hMLH1, combined with the gene's map position which is coincident with a previously identified HNPCC-linked locus, plus the likely role of the hMLH1 gene in mutation avoidance makes the hMLH1 gene a prime candidate for underlying one form of common inherited human cancer, and a prime candidate to screen and identify individuals who have an elevated risk of developing cancer.

hMLH1 has 19 exons and 18 introns. We have determined the location of each of the 18 introns relative to hMLH1 cDNA. We have also determined the structure of all intron/exon boundary regions of hMLH1. Knowledge of the intron/exon boundary structures makes possible efficient screening regimes to locate mutations which negatively affect the structure and function of gene products. Further, we have designed complete sets of oligonucleotide primer pairs which can be used in PCR to amplify individual complete exons together with surrounding intron boundary structures.

We mapped the location of hPMS1 to human chromosome 7. Subsequent studies by others³⁹ have confirmed our prediction that mutations in this gene are linked to HNPCC.

The most immediate use of the present invention will be in screening tests on human individuals who are members of families which exhibit an unusually high frequency of early onset cancer, for example HNPCC. Accordingly, one aspect of the invention comprises a method of diagnosing cancer susceptibility in a subject by detecting a mutation in a mismatch repair gene or gene product in a tissue from the subject, wherein the mutation is indicative of the subject's susceptibility to cancer. In a preferred embodiment of the invention, the step of detecting comprises detecting a mutation in a human mutL homolog gene, for example, hMLH1 of hPMS1.

The method of diagnosing preferably comprises the steps of: 1) amplifying a segment of the mismatch repair gene or gene product from an isolated nucleic acid; 2) comparing the amplified segment with an analogous segment of a wild-type allele of the mismatch repair gene or gene product; and 3) detecting a difference between the amplified segment and the analogous segment, the difference being indicative of a mutation in the mismatch repair gene or gene product which confers cancer susceptibility.

Another aspect of the invention provides methods of determining whether the difference between the amplified segment and the analogous wild-type segment causes an affected phenotype, i.e., does the sequence alteration affect the individual's ability to repair DNA mispairs.

The method of diagnosing may include the steps of: 1) reverse transcribing all or a portion of an RNA copy of a DNA mismatch repair gene; and 2) amplifying a segment of the DNA produced by reverse transcription. An amplifying step in the present invention may comprise: selecting a pair of oligonucleotide primers capable of hybridizing to opposite strands of the mismatch repair gene, in an opposite orientation; and performing a polymerase chain reaction utilizing the oligonucleotide primers such that nucleic acid of the mismatch repair chain intervening between the primers is amplified to become the amplified segment.

In preferred embodiments of the methods summarized above, the DNA mismatch repair gene is hMLH1 or hPMS1. The segment of DNA corresponds to a unique portion of a nucleotide sequence selected from the group consisting of SEQ. ID NOS: 6-24. "First stage" oligonucleotide primers selected from the group consisting of SEQ. ID NOS: 44-82 are used in PCR to amplify different exons from hMLH1. The invention also provides a method of using "second stage" nested primers (SEQ. ID NOS: 83-122), for use with the first stage primers to allow more specific amplification and conservation of template DNA.

Another aspect of the present invention provides a method of identifying and classifying a DNA mismatch repair defective tumor comprising detecting in a tumor a mutation in a mismatch repair gene or gene product, preferably a mutL homolog (hMLH1 or hPMS1), the mutation being indicative of a defect in a mismatch repair system of the tumor.

The present invention also provides useful nucleotide and protein compositions. One such composition is an isolated nucleotide or protein structure including a segment sequentially corresponding to a unique portion of a human mutL homolog gene or gene product, preferably derived from either hMLH1 or hPMS1.

Other composition aspects of the invention comprise oligonucleotide primers capable of being used together in a polymerase chain reaction to amplify specifically a unique segment of a human mutL homolog gene, preferably hMLH1 or hPMS1.

Another aspect of the present invention provides a probe including a nucleotide sequence capable of binding specifically by Watson/Crick pairing to complementary bases in a portion of a human mutL, homolog gene; and a label-moiety attached to the sequence, wherein the label-moiety has a property selected from the group consisting of fluorescent, radioactive and chemiluminescent.

We have also isolated and sequenced mouse MLH1 (mMLH1) and PMS1 (mPMS1) genes. cDNA structures of the mouse genes mMLH1 and mPMS1 are fully disclosed in the preceeding related patent application Ser. No. 08/209,521. We have used our knowledge of mouse mismatch repair genes to construct animal models for studying cancer. The models will be useful to identify additional oncogenes and to study environmental effects on mutagenesis.

We have produced polyclonal antibodies directed to a portion of the protein encoded by mPMS1 cDNA. The antibodies also react with hPMS1 protein and are useful for detecting the presence of the protein encoded by a normal hPMS1 gene. We are also producing monoclonal antibodies directed to hMLH1 and hPMS1.

In addition to diagnostic and therapeutic uses for the genes, our knowledge of hMLH1 and hPMS1 can be used to search for other genes of related function which are candidates for playing a role in certain forms of human cancer.

DEFINITIONS

gene--"Gene" means a nucleotide sequence that contains a complete coding sequence. Generally, "genes" also include nucleotide sequences found upstream (e.g. promoter sequences, enhancers, etc.) or downstream (e.g. transcription termination signals, polyadenylation sites, etc.) of the coding sequence that affect the expression of the encoded polypeptide.

gene product--A "gene product" is either a DNA or RNA (mRNA) copy of a portion of a gene, or a corresponding amino acid sequence translated from mRNA.

wild-type--The term "wild-type", when applied to nucleic acids and proteins of the present invention, means a version of a nucleic acid or protein that functions in a manner indistinguishable from a naturally-occurring, normal version of that nucleic acid or protein (i.e. a nucleic acid or protein with wild-type activity). For example, a "wild-type" allele of a mismatch repair gene is capable of functionally replacing a normal, endogenous copy of the same gene within a host cell without detectably altering mismatch repair in that cell. Different wild-type versions of the same nucleic acid or protein may or may not differ structurally from each other.

non-wild-type--The term "non-wild-type" when applied to nucleic acids and proteins of the present invention, means a version of a nucleic acid or protein that functions in a manner distinguishable from a naturally-occurring, normal version of that nucleic acid or protein. Non-wild-type alleles of a nucleic acid of the invention may differ structurally from wild-type alleles of the same nucleic acid in any of a variety of ways including, but not limited to, differences in the amino acid sequence of an encoded polypeptide and/or differences in expression levels of an encoded nucleotide transcript of polypeptide product.

For example, the nucleotide sequence of a non-wild-type allele of a nucleic acid of the invention may differ from that of a wild-type allele by, for example, addition, deletion, substitution, and/or rearrangement of nucleotides. Similarly, the amino acid sequence of a non-wild-type mismatch repair protein may differ from that of a wild-type mismatch repair protein by, for example, addition, substitution, and/or rearrangement of amino acids.

Particular non-wild-type nucleic acids or proteins that, when introduced into a normal host cell, interfere with the endogenous mismatch repair pathway, are termed "dominant negative" nucleic acids or proteins.

homologous--The term "homologous" refers to nucleic acids or polypeptides that are highly related at the level of nucleotide or amino acid sequence. Nucleic acids or polypeptides that are homologous to each other are termed "homologues".

The term "homologous"necessarily refers to a comparison between two sequences. In accordance with the invention, two nucleotide sequences are considered to be homologous if the polypeptides they encode are at least about 50-60% identical, preferably about 70% identical, for at least one stretch of at least 20 amino acids. Preferably, homologous nucleotide sequences are also characterized by the ability to encode a stretch of at least 4-5 uniquely specified amino acids. Both the identity and the approximate spacing of these amino acids relative to one another must be considered for nucleotide sequences to be considered to be homologous. For nucleotide sequences less than 60 nucleotides in length, homology is determined by the ability to encode a stretch of at least 4-5 uniquely specified amino acids.

upstream/downstream--The terms "upstream" and "downstream" are art-understood terms referring to the position of an element of nucleotide sequence. "Upstream" signifies an element that is more 5' than the reference element. "Downstream" refers to an element that is more 3' than a reference element.

intron/exon--The terms "exon" and "intron" are art-understood terms referring to various portions of genomic gene sequences. "Exons" are those portions of a genomic gene sequence that encode protein. "Introns" are sequences of nucleotides found between exons in genomic gene sequences.

affected--The term "affected", as used herein, refers to those members of a kindred that either have developed a characteristic cancer (e.g. colon cancer in an HNPCC lineage) and/or are predicted, on the basis of, for example, genetic studies, to carry an inherited mutation that confers susceptibility to cancer.

DESCRIPTION OF THE INVENTION

We have discovered mammalian genes which are involved in DNA mismatch repair. One of the genes, hPMS1, encodes a protein which is homologous to the yeast DNA mismatch repair protein PMS1. We have mapped the locations of hPMS1 to human chromosome 7 and the mouse PMS1 gene to mouse chromosome 5, band G. Another gene, hMLH1 (MutL Homolog) encodes a protein which is homologous to the yeast DNA mismatch repair protein MLH1. We have mapped the locations of hMLH1 to human chromosome 3p21.3-23 and to mouse chromosome 9, band E.

Studies¹,2 have demonstrated involvement of a human DNA mismatch repair gene homolog, hMSH2, on chromosome 2p in HNPCC. Based upon linkage data, a second HNPCC locus has been assigned to chromosome 3p21-23.³ Examination of tumor DNA from the chromosome 3-linked kindreds revealed dinucleotide repeat instability similar to that observed for other HNPCC families⁶ and several types of sporadic tumors.⁷⁻¹⁰ Because dinucleotide repeat instability is characteristic of a defect in DNA mismatch repair, ⁵, 11, 12 we reasoned that HNPCC linked to chromosome 3p21-23 could result from a mutation in a second DNA mismatch repair gene.

Repair of mismatched DNA in Escherichia coli requires a number of genes including mutS, mutL and mutH, defects in any one of which result in elevated spontaneous mutation rates.¹³ Genetic analysis in the yeast Saccharomyces cerevisiae has identified three DNA mismatch repair genes: a mutS homolog, MSH2,¹⁴ and two mutL homologs, PMS1¹⁶ and MLH1.⁴ Each of these three genes play an indispensable role in DNA replication fidelity, including the stabilization of dinucleotide repeats.⁵

We believe that hMLH1 is the HNPCC gene previously linked to chromosome 3p based upon the similarity of the hMLH1 gene product to the yeast DNA mismatch repair protein, MLH1,⁴ the coincident location of the hMLH1 gene and the HNPCC locus on chromosome 3, and hMLH1 missense mutations which we found in affected individuals from chromosome 3-linked HNPCC families.

Our knowledge of the human and mouse MLH1 and PMS1 gene structures has many important uses. The gene sequence information can be used to screen individuals for cancer risk. Knowledge of the gene structures makes it possible to easily design PCR primers which can be used to selectively amplify portions of hMLH1 and hPMS1 genes for subsequent comparison to the normal sequence and cancer risk analysis. This type of testing also makes it possible to search for and characterize hMLH1 and hPMS1 cancer-linked mutations for the purpose of eventually focusing the cancer screening effort on specific gene loci. Specific characterization of cancer-linked mutations in hMLH1 and hPMS1 makes possible the production of other valuable diagnostic tools such as allele specific probes which may be used in screening tests to determine the presence or absence of specific gene mutations.

Additionally, the gene sequence information for hMLH1 and/or hPMS1 can be used, for example, in a two hybrid system, to search for other genes of related function which are candidates for cancer involvement.

The hMLH1 and hPMS1 gene structures are useful for making proteins which are used to develop antibodies directed to specific portions or the complete hMLH1 and hPMS1 proteins. Such antibodies can then be used to isolate the corresponding protein and possibly related proteins for research and diagnostic purposes.

The mouse MLH1 and PMS1 gene sequences are useful for producing mice that have mutations in the respective gene. The mutant mice are useful for studying the gene's function, particularly its relationship to cancer.

Methods for Isolating and Characterizing Mammalian MLH1 and PMS1 Genes

We have isolated and characterized four mammalian genes, i.e., human MLH1 (hMLH1), human PMS1 (hPMS1), mouse MLH1 (mPMS1) and mouse PMS1 (mPMS1). Due to the structural similarity between these genes, the methods we have employed to isolate and characterize them are generally the same. FIG. 1 shows in broad terms, the experimental approach which we used to isolate and characterize the four genes. The following discussion refers to the step-by-step procedure shown in FIG. 1.

Step 1 Design of Degenerate Oligonucleotide Pools for PCR

Earlier reports indicated that portions of three MutL-like proteins, two from bacteria, MutL and HexB, and one from yeast, PMS1 are highly conserved.¹⁶,18,10 After inspection of the amino acid sequences of HexB, MutL and PMS1 proteins, as shown in FIG. 2, we designed pools of degenerate oligonucleotide pairs corresponding to two highly-conserved regions, KELVEN and GFRGEA, of the MutL-like proteins. The sequences (SEQ. ID NOS: 135 and 136, respectively) of the degenerate oligonucleotides which we used to isolate the four genes are:

5'-CTTGATTCTAGAGC(T/C)TCNCCNC(T/G)(A/G)AANCC-3' and

5'-AGGTCGGAGCTCAA(A/G)GA(A/G)(T/C)TNGTNGANAA-3'.

The underlined sequences within the primers are XbaI and SacI restriction endonuclease sites respectively. They were introduced in order to facilitate the cloning of the PCR-amplified fragments. In the design of the oligonucleotides, we took into account the fact that a given amino acid can be coded for by more than one DNA triplet (codon). The degeneracy within these sequences are indicated by multiple nucleotides within parentheses or N, for the presence of any base at that position.

Step 2 Reverse Transcription and PCR on Poly A+ Selected mRNA Isolated From Human Cells

We isolated messenger (poly A+ enriched) RNA from cultured human cells, synthesized double-stranded cDNA from the mRNA, and performed PCR with the degenerate oligonucleotides.⁴ After trying a number of different PCR conditions, for example, adjusting the annealing temperature, we successfully amplified a DNA of the size predicted (˜210 bp) for a MutL-like protein.

Step 3 Cloning and Sequencing of PCR-Generated Fragments; Identification of Two Gene Fragments Representing Human PMS1 and MLH1

We isolated the PCR amplified material (˜210 bp) from an agarose gel and cloned this material into a plasmid (pUC19). We determined the DNA sequence of several different clones. The amino acid sequence inferred from the DNA sequence of two clones showed strong similarity to other known MutL-like proteins.⁴,16,18,19 The predicted amino acid sequence for one of the clones was most similar to the yeast PMS1 protein. Therefore we named it hPMS1, for human PMS1. The second clone was found to encode a polypeptide that most closely resembles yeast MLH1 protein and was named, hMLH1, for human MLH1.

Step 4 Isolation of Complete Human and Mouse PMS1 and MLH1 cDNA Clones Using the PCR Fragments as Probes

We used the 210 bp PCR-generated fragments of the hMLH1 and hPMS1 cDNAs, as probes to screen both human and mouse cDNA libraries (from Stratagene, or as described in reference 30). A number of cDNAs were isolated that corresponded to these two genes. Many of the cDNAs were truncated at the 5' end. Where necessary, PCR techniques³¹ were used to obtain the 5'-end of the gene in addition to further screening of cDNA libraries. Complete composite cDNA sequences were used to predict the amino acid sequence of the human and mouse, MLH1 and PMS1 proteins.

Step 5 Isolation of Human and Mouse, PMS1 and MLH1 Genomic Clones

Information on genomic and cDNA structure of the human MLH1 and PMS1 genes are necessary in order to thoroughly screen for mutations in cancer prone families. We have used human cDNA sequences as probes to isolate the genomic sequences of human PMS1 and MLH1. We have isolated four cosmids and two P1 clones for hPMS1, that together are likely to contain most, if not all, of the cDNA (exon) sequence. For hMLH1 we have isolated four overlapping 1-phage clones containing 5'-MLH1 genomic sequences and four P1 clones (two full length clones and two which include the 5' coding end plus portions of the promoter region) P1 clone. PCR analysis using pairs of oligonucleotides specific to the 5' and 3' ends of the hMLH1 cDNA, clearly indicates that the P1 clone contains the complete hMLH1 cDNA information. Similarly, genomic clones for mouse PMS1 and MLH1 genes have been isolated and partially characterized (described in Step 8).

Step 6 Chromosome Positional Mapping of the Human and Mouse, PMS1 and MLH1 Genes by Fluorescence in situ Hybridization

We used genomic clones isolated from human and mouse PMS1 and MLH1 for chromosomal localization by fluorescence in situ hybridization (FISH).²⁰,21 We mapped the human MLH1 gene to chromosome 3p2 1.3-23, shown in FIG. 7 as discussed in more detail below. We mapped the mouse MLH1 gene to chromosome 9 band E, a region of synteny between mouse and human.²² In addition to FISH techniques, we used PCR with a pair of hMLH1-specific oligonucleotides to analyze DNA from a rodent/human somatic cell hybrid mapping panel (Coriell Institute for Medial Research, Camden, N.J.). Our PCR results with the panel clearly indicate that hMLH1 maps to chromosome 3. The position of hMLH1 3p21.3-23 is coincident to a region known to harbor a second locus for HNPCC based upon linkage data.

We mapped the hPMS1 gene, as shown in FIG. 12, to the long (q) arm of chromosome 7 (either 7q11 or 7q22) and the mouse PMS1 to chromosome 5 band G, two regions of synteny between the human and the mouse.²² We performed PCR using oligonucleotides specific to hPMS1 on DNA from a rodent/human cell panel. In agreement with the FISH data, the location of hPMS1 was confirmed to be on chromosome 7. These observations assure us that our human map position for hPMS1 to chromosome 7 is correct. The physical localization of hPMS1 is useful for the purpose of identifying families which may potentially have a cancer linked mutation in hPMS1.

Step 7 Using Genomic and cDNA Sequences to Identify Mutations in hPMS1 and hMLH1 Genes From HNPCC Families

We have analyzed samples collected from individuals in HNPCC families for the purpose of identifying mutations in hPMS1 or hMLH1 genes. Our approach is to design PCR primers based on our knowledge of the gene structures, to obtain exon/intron segments which we can compare to the known normal sequences. We refer to this approach as an "exon-screening".

Using cDNA sequence information we have designed and are continuing to design hPMS1 and hMLH1 specific oligonucleotides to delineate exon/intron boundaries within genomic sequences. The hPMS1 and hMLH1 specific oligonucleotides were used to probe genomic clones for the presence of exons containing that sequence. Oligonucleotides that hybridized were used as primers for DNA sequencing from the genomic clones. Exon-intron junctions were identified by comparing genomic with cDNA sequences.

Amplification of specific exons from genomic DNA by PCR and sequencing of the products is one method to screen HNPCC families for mutations.¹,2 We have identified genomic clones containing hMLH1 cDNA information and have determined the structures of all intron/exon boundary regions which flanks the 19 exons of hMCH1.

We have used the exon-screening approach to examine the MLH1 gene of individuals from HNPCC families showing linkage to chromosome 3.³ As will be discussed in more detail below, we identified a mutation in the MLH1 gene of one such family, consisting of a C to T substitution. We predict that the C to T mutation causes a serine to phenylalanine substitution in a highly-conserved region of the protein. We are continuing to identify HNPCC families from whom we can obtain samples in order to find additional mutations in hMLH1 and hPMS1 genes.

We are also using a second approach to identify mutations in hPMS1 and hMLH1. The approach is to design hPMS1 or hMLH1 specific oligonucleotide primers to produce first-strand cDNA by reverse transcription off RNA. PCR using gene-specific primers will allow us to amplify specific regions from these genes. DNA sequencing of the amplified fragments will allow us to detect mutations.

Step 8 Design Targeting Vectors to Disrupt Mouse PMS1 and MLH1 Genes in ES Cells; Study Mice Deficient in Mismatch Repair

We constructed a gene targeting vector based on our knowledge of the genomic mouse PMS1 DNA structure. We used the vector to disrupt the PMS1 gene in mouse embryonic stem cells.³⁶ The cells were injected into mouse blastocysts which developed into mice that are chimeric (mixtures) for cells carrying the PMS1 mutation. The chimeric animals will be used to breed mice that are heterozygous and homozygous for the PMS1 mutation. These mice will be useful for studying the role of the PMS1 gene in the whole organism.

Human MLH1

The following discussion is a more detailed explanation of our experimental work relating to hMLH1. As mentioned above, to clone mammalian MLH genes, we used PCR techniques like those used to identify the yeast MSH1, MSH2 and MLH1 genes and the human MSH2 gene.¹, 2, 4, 14 As template in the PCR, we used double-stranded cDNA synthesized from poly (A+) enriched RNA prepared from cultured primary human fibroblasts. The degenerate oligonucleotides were targeted at the N-terminal amino acid sequences KELVEN and GFRGEA (see FIG. 3), two of the most conserved regions of the MutL family of proteins previously described for bacteria and yeast.¹⁶,18,19 Two PCR products of the predicted size were identified, cloned and shown to encode a predicted amino acid sequence with homology to MutL-like proteins. These two fragments generated by PCR were used to isolate human cDNA and genomic DNA clones.

The oligonucleotide primers which we used to amplify human MutL-related sequences were 5'-CTTGATTCTAGAGC(T/C)TCNCCNC(T/G)(A/G)AANCC-3' (SEQ. ID NO: 135) and 5'-AGGTCGGAGCTCAA(A/G)GA(A/G)(T/C)TNGTNGANAA-3' (SEQ. ID NO: 136). PCR was carried out in 50 μL reactions containing cDNA template, 1.0 μM each primer, 5 IU of Taq polymerase (C) 50 mM KCl, 10 mM Tris buffer pH 7.5 and 1.5 mM MgCl. PCR was carried out for 35 cycles of 1 minute at 94° C., 1 minute at 43° C. and 1.5 minutes at 62° C. Fragments of the expected size, approximately 212 bp, were cloned into pUC19 and sequenced. The cloned MLH1 PCR products were labeled with a random primer labeling kit (RadPrime, Gibco BRL) and used to probe human cDNA and genomic cosmid libraries by standard procedures. DNA sequencing of double-stranded plasmid DNAs was performed as previously described.

The hMLH1 cDNA nucleotide sequence as shown in FIG. 3 encodes an open reading frame of 2268 bp. Also shown in FIG. 3 is the predicted protein sequence encoded for by the hMLH1 cDNA. The underlined DNA sequences are the regions of cDNA that correspond to the degenerate PCR plimers that were originally used to amplify a portion of the MLH1 gene (nucleotides 118-135 and 343-359).

FIG. 4A shows 19 nucleotide sequences corresponding to portions of hMLH1. Each sequence includes one of the 19 exons, in its entirety, surrounded by flanking intron sequences. Target PCR primer cites are underlined. More details relating to the derivation and uses of the sequences shown in FIG. 4A, are set forth below.

As shown in FIG. 5, the hMLH1 protein is comprised of 756 amino acids and shares 41% identity with the protein product of the yeast DNA mismatch repair gene, MLH1.⁴ The regions of the hMLH1 protein most similar to yeast MLH1 correspond to amino acids 11 through 317, showing 55% identity, and the last 13 amino acids which are identical between the two proteins. FIG. 5 shows an alignment of the predicted human MLH1 and S. cerevisiae MLH1 protein sequences. Amino acid identities are indicated by boxes, and gaps are indicated by dashes. The pair wise protein sequence alignment was performed with DNAStar MegAlign using the clustal method.²⁷ Pair wise alignment parameters were a ktuple of 1, gap penalty of 3, window of 5 and diagonals of 5.

FIG. 6 shows a phylogenetic tree of MutL-related proteins. The phylogenetic tree was constructed using the predicted amino acid sequences of 7 MutL-related proteins: human MLH1; mouse MLH1; S. cerevisiae MLH1; S. cerevisiae PMS1; E. coli; MutL; S. typhimurium MutL and S. pneumoniae HexB. Required sequences were obtained from GenBank release 7.3. The phylogenetic tree was generated with the PILEUP program of the Genetics Computer Group software using a gap penalty of 3 and a length penalty of 0.1. The recorded DNA sequences of hMLH1 and hPMS1 have been submitted to GenBank.

hMLH1 Intron Location and Intron/Exon Boundary Structures

In our previous U.S. patent application Ser. No. 08/209,521, we described the nucleotide sequence of a complimentary DNA (cDNA) clone of a human gene, hMLH1. The cDNA sequence of hMLH1 (SEQ. ID NO: 4) is presented in this application in FIG. 3. We note that there may be some variability between individuals hMLH1 cDNA structures, resulting from polymorphisms within the human population, and the degeneracy of the genetic code.

In the present application, we report the results of our genomic sequencing studies. Specifically, we have cloned the human genomic region that includes the hMLH1 gene, with specific focus on individual exons and surrounding intron/exon boundary structures. Toward the ultimate goal of designing a comprehensive and efficient approach to identify and characterize mutations which confer susceptibility to cancer, we believe it is important to know the wild-type sequences of intron structures which flank exons in the hMLH1 gene. One advantage of knowing the sequence of introns near the exon boundaries, is that it makes it possible to design primer pairs for selectively amplifying entire individual exons. More importantly, it is also possible that a mutation in an intron region, which, for example, may cause a mRNA splicing error, could result in a defective gene product, i.e., susceptibility to cancer, without showing any abnormality in an exon region of the gene. We believe a comprehensive screening approach requires searching for mutations, not only in the exon or cDNA, but also in the intrion structures which flank the exon boundaries.

We have cloned the human genomic region that includes hMLH1 using approaches which are known in the art, and other known approaches could have been used. We used PCR to screen a P1 human genomic library for the hMLH1 gene. We obtained four clones, two that contained the whole gene and two which lacked the C-terminus. We characterized one of the full length clones by cycle sequencing, which resulted in our definition of all intron/exon junction sequences for both sides of the 19 hMLH1 exons. We then designed multiple sets of PCR primers to amplify each individual exon (first stage primers) and verified the sequence of each exon and flanking intron sequence by amplifying several different genomic DNA samples and sequencing the resulting fragments using an ABI 373 sequencer. In addition, we have determined the sizes of each hMLH1 exon using PCR methods. Finally, we devised a set of nested PCR primers (second stage primers) for reamplification of individual exons. We have used the second stage primers in a multi-plex method for analyzing HNPCC families and tumors for hMLH1 mutations. Generally, in the nested PCR primer approach, we perform a first multi-plex amplification with four to eight sets of "first stage" primers, each directed to a different exon. We then reamplify individual exons from the product of the first amplification step, using a single set of second stage primers. Examples and further details relating to our use of the first and second stage primers are set forth below.

Through our genomic sequencing studies, we have identified all nineteen exons within the hMLH1 gene, and have mapped the intron/exon boundaries. One aspect of the invention, therefore, is the individual exons of the hMLH1 gene. Table 1 presents the nucleotide coordinates (i.e., the point of insertion of each intron within the coding region of the gene) of the hMLH1 exons (SEQ. ID NOS: 25-43). The presented coordinates are based on the hMLH1 cDNA sequence, assigning position "1" to the "A" of the start "ATG" (which A is nucleotide 1 in SEQ. ID NO: 4).

We have also determined the nucleotide sequence of intron regions which flank exons of the hMLH1 gene. SEQ. ID NOS: 6-24 are individual exon sequences bounded by their respective upstream and downstream intron sequences. The same nucleotide structures are shown in FIG. 4A, where the exons are numbered from N-terminus to C-terminus with respect to the chromosomal locus. The 5-digit numbers indicate the primers used to amplify the exon. All sequences are numbered assuming the A of the ATG codon is nucleotide 1. The numbers in () are the nucleotide coordinates of the coding sequence found in the indicated exon. Uppercase is intron. Lowercase is exon or non-translated sequences found in the mRNA/cDNA clone. Lowercase and underlined sequences correspond to primers. The stop codon at 2269-2271 is in italics and underlined.

Table 2 presents the sequences of primer pairs ("first stage" primers) which we have used to amplify individual exons together with flanking intron structures.

In Table 3 an asteric (*) indicates that the 5' nucleotide is biotinylated. Exons 1-7, 10, 13 and 16-19 can be specifically amplified in PCR reactions containing either 1.5 mM or 3 mM MgCl₂. Exons 11 and 14 can only be specifically amplified in PCR reactions containing 1.5 mM MgCl₂ and exons 8, 9, 12 and 15 can only be specifically amplified in PCR reactions containing 3 mM MgCL₂. With respect to exon 12, the second stage amplification primers have been designed so that exon 12 is reamplified in two halves. The 20546 and 20002 primer set amplifies the N-terminal half. The primer set 19829 and 19835 amplifies the C-terminal half. An alternate primer for 18178 is 19070.

The hMLH1 sequence information provided by our studies and disclosed in this application and preceding related applications, may be used to design a large number of different oligonucleotide primers for use in identifying hMLH1 mutations that correlate with cancer susceptibility and/or with tumor development in an individual, including primers that will amplify more than one exon (and/or flanking intron sequences) in a single product band.

One of ordinary skill in the art would be familiar with considerations important to the design of PCR primers for use to amplify the desired fragment or gene.³⁷ These considerations may be similar, though not necessarily identical to those involved in design of sequencing primers, as discussed above. Generally it is important that primers hybridize relatively specifically (i.e. have a T_(m) of greater than about 55° C., and preferably around 60° C.). For most cases, primers between about 17 and 25 nucleotides in length work well. Longer primers can be useful for amplifying longer fragments. In all cases, it is desirable to avoid using primers that are complementary to more than one sequence in the human genome, so that each pair of PCR primers amplifies only a single, correct fragment. Nevertheless, it is only absolutely necessary that the correct band be distinguishable from other product bands in the PCR reaction.

The exact PCR conditions (e.g. salt concentration, number of cycles, type of DNA polymerase, etc.) can be varied as known in the art to improve, for example, yield or specificity of the reaction. In particular, we have found it valuable to use nested primers in PCR reactions in order to reduce the amount of required DNA substrate and to improve amplification specificity.

Two examples follow. The first example illustrates use of a first stage primer pair (SEQ. ID NOS: 69 and 70) to amplify intron/exon segment (SEQ. ID NO: 18). The second example illustrates use of second stage primers to amplify a target intron/exon segment from the product of a first PCR amplification step employing first stage primers.

EXAMPLE 1 Amplification of hMLH1 Genomic Clones From a P1 Phage Library

25 ng genomic DNA (or 1 ng of a P1 phage can be used) was used in PCR reactions including:

0.05 mM dNTPs

50 mM KCl

3 mM Mg

10 mM Tris-HCl pH 8.5

0.01% gelatin

5 μM primers

Reactions were performed on a Perkin-Elmer Cetus model 9600 thermal cycler. Reactions were incubated at 95° C. for 5 minutes, followed by 35 cycles (30 cycles from a P1 phage) of:

94° C. for 30 seconds

55° C. for 30 seconds

72° C. for 1 minute.

A final 7 minute extension reaction was then performed at 72° C. Desirable P1 clones were those from which an approximately bp product band was produced.

EXAMPLE 2 Amplification of hMLH1 Sequences From Genomic DNA Using Nested PCR Primers

We performed two-step PCR amplification of hMLH1 sequences from genomic DNA as follows. Typically, the first amplification was performed in a 25 microliter reaction including:

25 ng of chromosomal DNA

Perkin-Elmer PCR buffer II (any suitable buffer could be used)

3 mM MgCl₂

50 mM each dNTP

Taq DNA polymerase

5 mM primers (SEQ. ID NOS: 69, 70)

and incubated at 95° C. for 5 minutes, followed by 20 cycles of:

94° C. for 30 seconds

55° C. for 30 seconds

The product band was typically small enough (less than an approximately 500 bp) that separate extension steps were not performed as part of each cycle. Rather, a single extension step was performed, at 72° C. for 7 minutes, after the 20 cycles were completed. Reaction products were stored at 4° C.

The second amplification reaction, usually 25 or 50 microliters in volume, included:

1 or 2 microliters (depending on the volume of the reaction) of the first amplification reaction product

Perkin-Elmer PCR buffer II (any suitable buffer could be used)

3 mM or MgCl₂

50 mM each dNTP

Taq DNA polymerase

5 mM nested primers (SEQ. ID NOS: 109, 110),

and was incubated at 95° C. for 5 minutes, followed by 20-25 cycles of:

94° C. for 30 seconds

55° C. for 30 seconds

a single extension step was performed, at 72° C. for 7 minutes, after the cycles were completed Reaction products were stored at 4° C.

Any set of primers capable of amplifying a target hMLH1 sequence can be used in the first amplification reaction. We have used each of the primer sets presented in Table 2 to amplify an individual hMLH1 exon in the first amplification reaction. We have also used combinations of those primer sets, thereby amplifying multiple individual hMLH1 exons in the first amplification reaction.

The nested primers used in the first amplification step were designed relative to the primers used in the first amplification reaction. That is, where a single set of primers is used in the first amplification reaction, the primers used in the second amplification reaction should be identical to the primers used in the first reaction except that the primers used in the second reaction should not include the 5'-most nucleotides of the first amplification reaction primers, and should extend sufficiently more at the 3' end that the T_(m) of the second amplification primers is approximately the same as the T_(m) of the first amplification reaction primers. Our second reaction primers typically lacked the 3 5'-most nucleotides of the first amplification reaction primers, and extended approximately 3-6 nucleotides farther on the 3' end. SEQ. ID NOS: 109, 110 are examples of nested primer pairs that could be used in a second amplification reaction when SEQ. ID NOS: 69 and 70 were used in the first amplification reaction.

We have also found that it can be valuable to include a standard sequence at the 5' end of one of the second amplification reaction primers to prime sequencing reactions. Additionally, we have found it useful to biotinylate that last nucleotide of one or both of the second amplification reaction primers so that the product band can easily be purified using magnetic beads⁴⁰ and then sequencing reactions can be performed directly on the bead-associated products.⁴¹⁻⁴⁵

hMLH1 Link to Cancer

As a first step to determine whether hMLH1 was a candidate for the HNPCC locus on human chromosome 3p21-23,³ we mapped hMLH1 by fluorescence in situ hybridization (FISH).²⁰,21 We used two separate genomic fragments (data not shown) of the hMLH1 gene in FISH analysis. Examination of several metaphase chromosome spreads localized hMLH1 to chromosome 3p21.3-23.

Panel A of FIG. 7 shows hybridization of hMLH1 probes in a metaphase spread. Biotinylated hMLH1 genomic probes were hybridized to banded human metaphase chromosomes as previously described.²⁰,21 Detection was performed with fluorescein isothiocyanate (FITC)-conjugated avidin (green signal); chromosomes, shown in blue, were counterstained with 4'6-diamino-2-phenylindole (DAPI). Images were obtained with a cooled CCD camera, enhanced, pseudocoloured and merged with the following programs: CCD Image Capture; NIH Image 1.4; Adobe Photoshop and Genejoin Maxpix respectively. Panel B of FIG. 7 shows a composite of chromosome 3 from multiple metaphase spreads aligned with the human chromosome 3 ideogram. Region of hybridization (distal portion of 3p21.3-23) is indicated in the ideogram by a vertical bar.

As independent confirmation of the location of hMLH1 on chromosome 3, we used both PCR with a pair of hMLH1-specific oligonucleotides and Southern blotting with a hMLH1-specific probe to analyze DNA from the NIGMS2 rodent/human cell panel (Coriell Inst. for Med. Res., Camden, N.J., U.S.A.). Results of both techniques indicated chromosome 3 linkage. We also mapped the mouse MLH1 gene by FISH to chromosome 9 band E. This is a position of synteny to human chromosome 3p.²² Therefore, the hMLH1 gene localizes to 3p21.3-23, within the genomic region implicated in chromosome 3-linked HNPCC families.³

Next, we analyzed blood samples from affected and unaffected individuals from two chromosome-3 candidate HNPCC families³ for mutations. One family, Family 1, showed significant linkage (lod score=3.01 at recombination fraction of 0) between HNPCC and a marker on 3p. For the second family, Family 2, the reported lod score (1.02) was below the commonly accepted level of significance, and thus only suggested linkage to the same marker on 3p. Subsequent linkage analysis of Family 2 with the microsatellite marker D3S1298 on 3p21.3 gave a more significant lod score of 1.88 at a recombination fraction of 0. Initially, we screened for mutations in two PCR-amplified exons of the hMLH1 gene by direct DNA sequencing (FIG. 4). We examined these two exons from three affected individuals of Family 1, and did not detect any differences from the expected sequence. In Family 2, we observed that four individuals affected with colon cancer are heterozygous for a C to T substitution in an exon encoding amino acids 41-69, which corresponds to a highly-conserved region of the protein (FIG. 9). For one affected individual, we screened PCR-amplified cDNA for additional sequence differences. The combined sequence information obtained from the two exons and cDNA of this one affected individual represents 95% (i.e. all but the first 116 bp) of the open reading frame. We observed no nucleotide changes other than the C to T substitution. In addition, four individuals from Family 2, predicted to be carriers based upon linkage data, and as yet unaffected with colon cancer, were found to be heterozygous for the same C to T substitution. Two of these predicted carriers are below and two are above the mean age of onset (50 years) in this particular family. Two unaffected individuals examined from this same family, both predicted by linkage data to be non carriers, showed the expected normal sequence at this position. Linkage analysis that includes the C to T substitution in Family 2 gives a lod score of 2.23 at a recombination fraction 0. Using low stringency cancer diagnostic criteria, we calculated a lod score of 2.53. These data indicate the C to T substitution shows significant linkage to the HNPCC in Family 2.

FIG. 8 shows sequence chromatograms indicating a C to T transition mutation that produces a non-conservative amino acid substitution at position 44 of the hMLHL1 protein. Sequence analysis of one unaffected (top panels, plus and minus strands) and one affected individual (lower panels, plus and minus strands) is presented. The position of the heterozygous nucleotide is indicated by an arrow. Analysis of the sequence chromatographs indicates that there is sufficient T signal in the C peak and enough A signal in the G peak for the affected individuals to be heterozygous at this site.

To determine whether this C to T substitution was a polymorphism, we sequenced this same exon amplified from the genomic DNA from 48 unrelated individuals and observed only the normal sequence. We have examined an additional 26 unrelated individuals using allele specific oligonucleotide (ASO) hybridization analysis.³³ The ASO sequences (SEQ. ID NOS: 137 and 138, respectively) which we used are:

5'-ACTTGTGGATTTTGC-3' and

5'-ACTTGTGAATTTTGC-3'.

Based upon direct DNA sequencing and ASO analysis, none of these 74 unrelated individuals carry the C to T substitution. Therefore, the C to T substitution observed in Family 2 individuals is not likely to be a polymorphism. As mentioned above, we did not detect this same C to T substitution in affected individuals from a second chromosome 3-linked family, Family 1.³ We are continuing to study individuals of Family 1 for mutations in hMLH1.

Table 4 below summarizes our experimental analysis of blood samples from affected and unaffected individuals from Family 2 and unrelated individuals.

                  TABLE 4                                                          ______________________________________                                                         Number of                                                         Individuals                                                                    with C to T                                                                    Mutation/Number                                                               Status of Individuals Tested                                                 ______________________________________                                         Family 2                                                                          Affected 4/4                                                                   Predicted Carriers 4/4                                                         Predicted Non-carriers 0/2                                                    Unrelated Individuals  0/74                                                  ______________________________________                                    

Based on several criteria, we suggest that the observed C to T substitution in the coding region of hMLH1 represents the mutation that is the basis for HNPCC in Family 2.³ First, DNA sequence and ASO analysis did not detect the C to T substitution in 74 unrelated individuals. Thus, the C to T substitution is not simply a polymorphism. Second, the observed C to T substitution is expected to produce a serine to phenylalanine change at position 44 (See FIG. 9). This amino acid substitution is a non-conservative change in a conserved region of the protein (FIGS. 3 and 9). Secondary structure predictions using Chou-Fasman parameters suggest a helix-turn-beta sheet structure with position 44 located in the turn. The observed Ser to Phe substitution, at position 44 lowers the prediction for this turn considerably, suggesting that the predicted amino acid substitution alters the conformation of the hMLH1 protein. The suggestion that the Ser to Phe substitution is a mutation which confers cancer susceptibility is further supported by our experiments which show that an analogous substitution (alanine to phenylalanine) in a yeast MLH1 gene results in a nonfunctional mismatch repair protein. In bacteria and yeast, a mutation affecting DNA mismatch repair causes comparable increases in the rate of spontaneous mutation including additions and deletions within dinucleotide repeats.⁴,5,11,13,14,15,16 In humans, mutation of hMSH2 is the basis of chromosome-2 HNPCC,¹,2 tumors which show microsatellite instability and an apparent defect in mismatch repair.¹² Chromosome 3-linked HNPCC is also associated with instability of dinucleotide repeats.³ Combined with these observations, the high degree of conservation between the human MLH1 protein and the yeast DNA mismatch repair protein MLH1 suggests that hMLH1 is likely to function in DNA mismatch repair. During isolation of the hMLH1 gene, we identified the hPMS1 gene. This observation suggests that mammalian DNA mismatch repair, like that in yeast,⁴ may require at least two MutL-like proteins.

It should be noted that it appears that different HNPCC families show different mutations in the MLH1 gene. As explained above, affected individuals in Family 1 showed "tight linkage" between HNPCC and a locus in the region of 3p21-23. However, affected individuals in Family 1 do not have the C to T mutation found in Family 2. It appears that the affected individuals in Family 1 have a different mutation in their MLH1 gene. Further, we have used the structure information and methods described in this application to find and characterize another hMLH1 mutation which apparently confers cancer susceptibility in heterozygous carriers of the mutant gene in a large English HNPCC family. The hMLH1 mutation in the English family is a +1 T frameshift which is predicted to lead to the synthesis of a truncated hMLH1 protein. Unlike, for example, sickle cell anemia, in which essentially all known affected individuals have the same mutation multiple hMLH1 mutations have been discovered and linked to cancer. Therefore, knowledge of the entire cDNA sequence for hMLH1 (and probably hPMS1), as well as genomic sequences particularly those that surround exons, will be useful and important for characterizing mutations in families identified as exhibiting a high frequency of cancer.

Subsequent to our discovery of a cancer conferring mutation in hMLH1, studies by others have resulted in the characterization of at least 5 additional mutations in hMLH1, each of which appears to have conferred cancer susceptibility to individuals in at least one HNPCC family. For example, Papadopoulos et al. indentified such a mutation, characterized by an in-frame deletion of 165 base pairs between codons 578 to 632. In another family, Papadopoulos et al. observed an hMLH1 mutation, characterized by a frame shift and substitution of new amino acids, namely, a 4 base pair deletion between codons 727 and 728. Papadopoulos et al. also reports an hMLH1 cancer linked mutation, characterized by an extension of the COOH terminus, namely, a 4 base pair insertion between codons 755 and 756.³⁸

In summary, we have shown that DNA mismatch repair gene hMLH1 which is likely to be the hereditary nonpolyposis colon cancer gene previously localized by linkage analysis to chromosome 3p21-23.³ Availability of the hMLH1 gene sequence will facilitate the screening of HNPCC families for cancer-linked mutations. In addition, although loss of heterozygosity (LOH) of linked markers is not a feature of either the 2p or 3p forms of HNPCC,³,6 LOH involving the 3p21.3-23 region has been observed in several human cancers.²⁴⁻²⁶ This suggests the possibility that hMLH1 mutation may play some role in these tumors.

Human PMS1

Human PMS1 was isolated using the procedures discussed with reference to FIG. 1. FIG. 10 shows the entire hPMS1 cDNA nucleotide sequence. FIG. 11 shows an alignment of the predicted human and yeast PMS1 protein sequences. We determined by FISH analysis that human PMS1 is located on chromosome 7. Subsequent to our discovery of hPMS1, others have identified mutations in the gene which appear to confer HNPCC susceptibility.³⁹

Distinguishing Mutations From Polymorphisms

For studies of cancer susceptibility and for tumor identification and characterization, it is important to distinguish "mutations" from "polymorphisms". A "mutation" produces a "non-wild-type allele" of a gene. A non-wild-type allele of a gene produces a transcript and/or a protein product that does not function normally within a cell. "Mutations" can be any alteration in nucleotide sequence including insertions, deletions, substitutions, and rearrangements.

"Polymorphisms", on the other hand, are sequence differences that are found within the population of normally-functioning (i.e., "wild-type") genes. Some polymorphisms result from the degeneracy of the nucleic acid code. That is, given that most amino acids are encoded by more than one triplet codon, many different nucleotide sequences can encode the same polypeptide. Other polymorphisms are simply sequence differences that do not have a significant effect on the function of the gene or encoded polypeptide. For example, polypeptides can often tolerate small insertions or deletions, or "conservative" substitutions in their amino acid sequence without significantly altering function of the polypeptide.

"Conservative" substitutions are those in which a particular amino acid is substituted by another amino acid of similar chemical characteristics. For example, the amino acids are often characterized as "non-polar (hydrophobic)" including alanine, leucine, isoleucine, valine, proline, phenylaline, typtophan, and methionine; "polar neutral", including glycine, serine, threonine, cysteine, tyrosine, asparagine, and glutamine; "positively charged (basic)", including arginine, lysine, and histidine; and "negatively charged (acidic)", including aspartic acid and glutamic acid. A substitution of one amino acid for another amino acid in the same group is generally considered to be "conservative", particularly if the side groups of the two relevant amino acids are of a similar size.

The first step in identifying a mutation or polymorphism in a mismatch repair gene sequence involves identification, using available techniques including those described herein, of a mismatch repair gene, (or gene fragment) sequence that differs from a known, normal (e.g. wild-type) sequence of the same mismatch repair gene (or gene fragment). For example, a hMLH1 gene (or gene fragment) sequence could be identified that differs in at least one nucleotide position from a known normal (e.g. wild-type) hMLH1 sequence such as any of SEQ. ID NOS: 6-24.

Mutations can be distinguished from polymorphisms using any of a variety of methods, perhaps the most direct of which is data collection and correlation with tumor development. That is, for example, a subject might be identified whose hMLH1 gene sequence differs from a sequence reported in SEQ. ID NOS: 6-24, but who does not have cancer and has no family history of cancer. Particularly if other, preferably senior, members of that subject's family have hMLH1 gene sequences that differ from SEQ. ID NOS: 6-24 in the same way(s), it is likely that subject's hMLH1 gene sequence could be categorized as a "polymorphism". If other, unrelated individuals are identified with the same hMLH1 gene sequence and no family history of cancer, the categorization may be confirmed.

Mutations that are responsible for conferring genetic susceptibility to cancer can be identified because, among other things, such mutations are likely to be present in all tissues of an affected individual and in the germ line of at least one of that individual's parents, and are not likely to be found in unrelated families with no history of cancer.

When distinguishing mutations from polymorphisms, it can sometimes be valuable to evaluate a particular sequence difference in the presence of at least one known mismatch repair gene mutation. In some instances, a particular sequence change will not have a detectable effect (i.e., will appear to be a polymorphism) when assayed alone, but will, for example, increase the penetrance of a known mutation, such that individuals carrying both the apparent polymorphism difference and a known mutation have higher probability of developing cancer than do individuals carrying only the mutation. Sequence differences that have such an effect are properly considered to be mutations, albeit weak ones.

As discussed above and previously (U.S. patent application Ser. Nos. 08/168,877 and 08/209,521), mutations in mismatch repair genes or gene products produced non-wild-type versions of those genes or gene products. Some mutations can therefore be distinguished from polymorphisms by their functional characteristics in in vivo or in vitro mismatch repair assays. Any available mismatch repair assay can be used to analyze these characteristics.⁴⁹⁻⁶³ It is generally desirable to utilize more than one mismatch repair assay before classifying a sequence change as a polymorphism, since some mutations will have effects that will not be observed in all assays.

For example, a mismatch repair gene containing a mutation would not be expected to be able to replace an endogenous copy of the same gene in a host cell without detectably affecting mismatch repair in that cell; whereas a mismatch repair gene containing a sequence polymorphism would be expected to be able to replace an endogenous copy of the same gene in a host cell without detectably affecting mismatch repair in that cell. We note that for such "replacement" studies, it is generally desirable to introduce the gene to be tested into a host cell of the same (or at least closely related) species as the cell from which the test gene was derived, to avoid complications due to, for example, the inability of a gene product from one species to interact with other mismatch repair gene products from another species. Similarly, a mutant mismatch repair protein would not be expected to function normally in an in vitro mismatch repair system (preferably from a related organism); whereas a polymorphic mismatch repair protein would be expected to function normally.

The methods described herein and previously allow identification of different kinds of mismatch repair gene mutations. The following examples illustrate protocols for distinguishing mutations from polymorphisms in DNA mismatch repair genes.

EXAMPLE 3

We have developed a system for testing in yeast, S. cerevisiae the functional significance of mutations found in either the hMLH1 or hPMS1 genes. The system is described in this application using as an example, the serine (SER) to phenylalanine (PHE) causing mutation in hMLH1 that we found in a family with HNPCC, as described above. We have derived a yeast strain that it is essentially deleted for its MLH1 gene and hence is a strong mutator i.e., 1000 fold above the normal rate in a simple genetic marker assay involving reversion from growth dependence on a given amino acid to independence (reversion of the hom3-10 allele, Prolla, Christie and Liskay, Mol Cell Biol, 14:407-415, 1994). When we placed the normal yeast MLH1 gene (complete with all known control regions) on a yeast plasma that is stably maintained as a single copy into the MLH1-deleted strain, the mutator phenotype is fully corrected using the reversion to amino acid independence assay. However, if we introduce a deleted copy of the yeast MLH1 there is no correction. We next tested the mutation that in the HNPCC family caused a SER to PHE alteration. We found that the resultant mutant yeast protein cannot correct the mutator phenotype, strongly suggesting that the alteration from the wild-type gene sequence probably confers cancer susceptibility, and is therefore classified as a mutation, not a polymorphism. We subsequently tested proteins engineered to contain other amino acids at the "serene" position and found that most changes result in a fully mutant, or at least partially mutant phenotype.

As other "point" mutations in MLH1 and PMS1 genes are found in cancer families, they can be engineered into the appropriate yeast homolog gene and their consequence on protein function studied. In addition, we have identified a number of highly conserved amino acids in both the MLH1 and PMS1 genes. We also have evidence that hMLH1 interacts with yeast PMS1. This finding raises the possibility that mutations observed in the hMLH1 gene can be more directly tested in the yeast system. We plan to systematically make mutations that will alter the amino acid at these conserved positions and determine what amino acid substitutions are tolerated and which are not. By collecting mutation information relating to hMLH1 and hPMS1, both by determining and documenting actual found mutations in HNPCC families, and by artificially synthesizing mutants for testing in experimental systems, it may be eventually possible to practice a cancer susceptibility testing protocol which, once the individuals hMLH1 or hPMS1 structure is determined, only requires comparison of that structure to known mutation versus polymorphism data.

EXAMPLE 4

Another method which we have employed to study physical interactions between hMLH1 and hPMS1, can also be used to study whether a particular alteration in a gene product results in a change in the degree of protein-protein interaction. Information concerning changes in protein-protein interaction may demonstrate or confirm whether a particular genomic valiation is a mutation or a polymorphism. Following our labs findings on the interaction between yeast MLH1 and PMS1 proteins in vitro and in vivo, (U.S. patent application Ser. No. 08/168,877), the interaction between the human counterparts of these two DNA mismatch repair proteins was tested. The human MLH1 and human PMS1 proteins were tested for in vitro interaction using maltose binding protein (MBP) affinity chromatography. hMLH1 protein was prepared as an MBP fusion protein, immobilized on an amylose resin column via the MBP, and tested for binding to hPMS1, synthesized in vitro. The hPMS1 protein bound to the MBP-hMLH1 matrix, whereas control proteins showed no affinity for the matrix. When the hMLH1 protein, translated in vitro, was passed over an MBP-hPMS1 fusion protein matrix, the hMLH1 protein bound to the MBP-hPMS1 matrix, whereas control proteins did not.

Potential in vivo interactions between hMLH1 and hPMS1 were tested using the yeast "two hybrid" system.² Our initial results indicate that hMLH1 and hPMS1 interact in vivo in yeast. The same system can also be used to detect changes in protein-protein interaction which result from changes in gene or gene product structure and which have yet to be classified as either a polymorphism or a mutation which confers cancer susceptibility.

Detection of HNPCC Families and Their Mutation(s)

It has been estimated that approximately 1,000,000 individuals in the United States carry (are heterozygous for) an HNPCC mutant gene.²⁹ Furthermore, estimates suggest that 50-60% of HNPCC families segregate mutations in the MSH2 gene that resides on chromosome 2p.¹,2 Another significant fraction appear to be associated with the HNPCC gene that maps to chromosome 3p21-22, presumably due to hMLH1 mutations such as the C to T transition discussed above. Identification of families that segregate mutant alleles of either the hMSH2 or hMLH1 gene, and the determination of which individuals in these families actually have the mutation will be of great utility in the early intervention into the disease. Such early intervention will likely include early detection through screening and aggressive follow-up treatment of affected individuals. In addition, determination of the genetic basis for both familial and sporadic tumors could direct the method of therapy in the primary tumor, or in recurrences.

Initially, HNPCC candidate families will be diagnosed partly through the study of family histories, most likely at the local level, e.g., by hospital oncologists. One criterion for HNPCC is the observation of microsatellite instability in individual's tumors.³,6 The presenting patient would be tested for mutations in hMSH2, hMLH1, hPMS1 and other genes involved in DNA mismatch repair as they are identified. This is most easily done by sampling blood from the individual. Also highly useful would be freshly frozen tumor tissue. It is important to note for the screening procedure, that affected individuals are heterozygous for the offending mutation in their normal tissues.

The available tissues, e.g., blood and tumor, are worked up for PCR-based mutation analysis using one or both of the following procedures:

1) Linkage Analysis With a Microsatellite Marker Tightly Linked to the hMLH1 Gene

One approach to identify cancer prone families with a hMLH1 mutation is to perform linkage analysis with a highly polymorphic marker located within or tightly linked to hMLH1. Microsatellites are highly polymorphic and therefore are very useful as markers in linkage analysis. Because we possess the hMLH1 gene on a single large genomic fragment in a P1 phage clone (˜100 kbp), it is very likely that one or more microsatellites, e.g. tracts of dinucleotide repeats, exist within, or very close to, the hMLH1 gene. At least one such microsatellite has been reported.³⁸ Once such markers have been identified, PCR primers will be designed to amplify the stretches of DNA containing the microsatellites. DNA of affected and unaffected individuals from a family with a high frequency of cancer will be screened to determine the segregation of the MLH1 markers and the presence of cancer. The resulting data can be used to calculate a lod score and hence determine the likelihood of linkage between hMLH1 and the occurrence of cancer. Once linkage is established in a given family, the same polymorphic marker can be used to test other members of the kindred for the likelihood of their carrying the hMLH1 mutation.

2) Sequencing of Reverse Transcribed cDNA

a) RNA from affected individuals, unaffected and unrelated individuals is reverse transcribed (RT'd), followed by PCR to amplify the cDNA in 4-5 overlapping portions.³⁴,37 It should be noted that for the purposes of PCR, many different oligonucleotide primer pair sequences may potentially be used to amplify relevant portions of an individual's hMLH1 or hPMS1 gene for genetic screening purposes. With the knowledge of the cDNA structures for the genes, it is a straight-forward exercise to construct primer pairs which are likely to be effective for specifically amplifying selected portions of the gene. While primer sequences are typically between 20 to 30 bases long, it may be possible to use shorter primers, potentially as small as approximately 13 bases, to amplify specifically selected gene segments. The principal limitation on how small a primer sequence may be is that it must be long enough to hybridize specifically to the targeted gene segment. Specificity of PCR is generally improved by lengthening primers and/or employing nested pairs of primers.

The PCR products, in total representing the entire cDNA, are then sequenced and compared to known wild-type sequences. In most cases a mutation will be observed in the affected individual. Ideally, the nature of mutation will indicate that it is likely to inactivate the gene product. Otherwise, the possibility that the alteration is not simply a polymorphism must be determined.

b) Certain mutations, e.g., those affecting splicing or resulting in translation stop codons, can destabilize the messenger RNA produced from the mutant gene and hence comprise the normal RT-based mutation detection method. One recently reported technique can circumvent this problem by testing whether the mutant cDNA can direct the synthesis of normal length protein in a coupled in vitro transcription/translation system.³²

3) Direct Sequencing of Genomic DNA

A second route to detect mutations relies on examining the exons and the intron/exon boundaries by PCR cycle sequencing directly off a DNA template.¹,2 This method requires the use of oligonucleotide pairs, such as those described in Tables 2 and 3 above, that amplify individual exons for direct PCR cycle sequencing. The method depends upon genomic DNA sequence information at each intron/exon boundary (50 bp, or greater, for each boundary). The advantage of the technique is two fold. First, because DNA is more stable than RNA, the condition of the material used for PCR is not as important as it is for RNA-based protocols. Second, most any mutation within the actual transcribed region of the gene, including those in an intron affecting splicing, will be detectable.

For each candidate gene, mutation detection may require knowledge of both the entire cDNA structure, and all intron/exon boundaries of the genomic structure. With such information, the type of causal mutation in a particular family can be determined. In turn, a more specific and efficient mutation detection scheme can be adapted for the particular family. Screening for the disease (HNPCC) is complex because it has a genetically heterogeneous basis in the sense that more than one gene is involved, and for each gene, multiple types of mutations are involved.² Any given family is highly likely to segregate one particular mutation. However, as the nature of the mutation in multiple families is determined, the spectrum of the most prevalent mutations in the population will be determined. In general, determination of the most frequent mutations will direct and streamline mutation detection.

Because HNPCC is so prevalent in the human population, carrier detection at birth could become part of standardized neonatal testing. Families at risk can be identified and all members not previously tested can be tested. Eventually, all affected kindreds could be determined.

Mode of Mutation Screening and Testing

DNA-Based Testing

Initial testing, including identifying likely HNPCC families by standard diagnosis and family history study, will likely be done in local and smaller DNA diagnosis laboratories. However, large scale testing of multiple family members, and certainly population wide testing, will ultimately require large efficient centralized commercial facilities.

Tests will be developed based on the determination of the most common mutations for the major genes underlying HNPCC, including at least the hMSH2 gene on chromosome 2p and the MLH1 gene on chromosome 3p. A variety of tests are likely to be developed. For example, one possibility is a set of tests employing oligonucleotide hybridizations that distinguish the normal vs. mutant alleles.³³ As already noted, our knowledge of the nucleotide structures for hMLH1, hPMS1 and hMSH2 genes makes possible the design of numerous oligonucleotide primer pairs which may be used to amplify specific portions of an individual's mismatch repair gene for genetic screening and cancer risk analysis. Our knowledge of the genes' structures also makes possible the design of labeled probes which can be quickly used to determine the presence or absence of all or a portion of one of the DNA mismatch repair genes. For example, allele-specific oligomer probes (ASO) may be designed to distinguish between alleles. ASOs are short DNA segments that are identical in sequence except for a single base difference that reflects the difference between normal and mutant alleles. Under the appropriate DNA hybridization conditions, these probes can recognize a single base difference between two otherwise identical DNA sequences. Probes can be labeled radioactively or with a variety of non-radioactive reporter molecules, for example, fluorescent or chemiluminescent moieties. Labeled probes are then used to analyze the PCR sample for the presence of the disease-causing allele. The presence or absence of several different disease-causing genes can readily be determined in a single sample. The length of the probe must be long enough to avoid non-specific binding to nucleotide sequences other than the target. All tests will depend ultimately on accurate and complete structural information relating to hMLH1, hMSH2, hPMS1 and other DNA mismatch repair genes implicated in HNPCC.

Protein Detection-Based Screening

Tests based on the functionality of the protein product, per se, may also be used. The protein-examining tests will most likely utilize antibody reagents specific to either the hMLH1, hPMS1 and hMSH2 proteins or other related "cancer" gene products as they are identified.

For example, a frozen tumor specimen can be cross-sectioned and prepared for antibody staining using indirect fluorescence techniques. Certain gene mutations are expected to alter or destabilize the protein structure sufficiently such as to give an altered or reduced signal after antibody staining. It is likely that such tests will be performed in cases where gene involvement in a family's cancer has yet to be established. We are in the process of developing diagnostic monoclonal antibodies against the human MLH1 and PMS1 proteins. We are overexpressing MLH1 and PMS1 human proteins in bacteria. We will purify the proteins, inject them into mice and derive protein specific monoclonal antibodies which can be used for diagnostic and research purposes.

Identification and Characterization of DNA Mismatch Repair Tumors

In addition to their usefulness in diagnosing cancer susceptibility in a subject, nucleotide sequences that are homologous to a bacterial mismatch repair gene can be valuable for, among other things, use in the identification and characterization of mismatch-repair-defective tumors. Such identification and characterization is valuable because mismatch-repair-defective tumors may respond better to particular therapy regimens. For example, mismatch-repair-defective tumors might be sensitive to DNA damaging agents, especially when administered in combination with other therapeutic agents.

Defects in mismatch repair genes need not be present throughout an individual's tissues to contribute to tumor formation in that individual. Spontaneous mutation of a mismatch repair gene in a particular cell or tissue can contribute to tumor formation in that tissue. In fact, at least in some cases, a single mutation in a mismatch repair gene is not sufficient for tumor development. In such instances, an individual with a single mutation in a mismatch repair gene is susceptible to cancer, but will not develop a tumor until a secondary mutation occurs. Additionally, in some instances, the same mismatch repair gene mutation that is strictly tumor-associated in an individual will be responsible for conferring cancer susceptibility in a family with a hereditary predisposition to cancer development.

In yet another aspect of the invention, the sequence information we have provided can be used with methods known in the art to analyze tumors (or tumor cell lines) and to identify tumor-associated mutations in mismatch repair genes. Preferably, it is possible to demonstrate that these tumor-associated mutations are not present in non-tumor tissues from the same individual. The information described in this application is particularly useful for the identification of mismatch repair gene mutations within tumors (or tumor cell lines) that display genomic instability of short repeated DNA elements.

The sequence information and testing protocols of the present invention can also be used to determine whether two tumors are related, i.e., whether a second tumor is the result of metastasis from an earlier found first tumor which exhibits a particular DNA mismatch repair gene mutation.

Isolating Additional Genes of Related Function

Proteins that interact physically with either hMLH1 and/or hPMS1, are likely to be involved in DNA mismatch repair. By analogy to hMLH1 and hMSH2, mutations in the genes which encode for such proteins would be strong candidates for potential cancer linkage. A powerfull molecular genetic approach using yeast, referred to as a "two-hybrid system", allows the relatively rapid detection and isolation of genes encoding proteins that interact with a gene product of interest, e.g., hMLH1.²⁸

The two-hybrid system involves two plasmid vectors each intended to encode a fusion protein. Each of the two vectors contains a portion, or domain, of a transcription activator. The yeast cell used in the detection scheme contains a "reporter" gene. The activator alone cannot activate transcription. However, if the two domains are brought into close proximity then transcription may occur. The cDNA for the protein of interest, e.g., hMLH1 is inserted within a reading frame in one of the vectors. This is termed the "bait". A library of human cDNAs, inserted into a second plasmid vector so as to make fusions with the other domain of the transcriptional activator, is introduced into the yeast cells harboring the "bait" vector. If a particular yeast cell receives a library member that contains a human cDNA encoding a protein that interacts with hMLH1 protein, this interaction will bring the two domains of the transcriptional activator into close proximity, activate transcription of the reporter gene and the yeast cell will turn blue. Next, the insert is sequenced to determine whether it is related to any sequence in the data base. The same procedure can be used to identify yeast proteins in DNA mismatch repair or a related process. Performing the yeast and human "hunts" in parallel has certain advantages. The function of novel yeast homologs can be quickly determined in yeast by gene disruption and subsequent examination of the genetic consequences of being defective in the new found gene. These yeast studies will help guide the analysis of novel human "hMLH1-or hPMS1-interacting" proteins in much the same way that the yeast studies on PMS1 and MLH1 have influenced our studies of the human MLH1 and PMS1 genes.

Production of Antibodies

By using our knowledge of the DNA sequences for hMLH1 and hPMS1, we can synthesize all or portions of the predicted protein structures for the purpose of producing antibodies. One important use for antibodies directed to hMLH1 and hPMS1 proteins will be for capturing other proteins which may be involved in DNA mismatch repair. For example, by employing coimmuno-precipitation techniques, antibodies directed to either hMLH1 or hPMS1 may be precipitated along with other associated proteins which are functionally and/or physically related. Another important use for antibodies will be for the purpose of isolating hMLH1 and hPMS1 proteins from tumor tissue. The hMLH1 and hPMS1 proteins from tumors can then be characterized for the purpose of determining appropriate treatment strategies.

As already mentioned, we are in the process of developing monoclonal antibodies directed to the hMLH1 and hPMS1 proteins. As discussed in prior U.S. patent application Ser. No. 08/209,521, we have produced polyclonal antibodies directed to the human and mouse forms of PMS1 protein.

DNA Mismatch Repair Defective Mice

In order to create a experimental model system for studying DNA mismatch repair defects and resultant cancer in a whole animal system we have derived DNA mismatch repair defective mice using embryonic stem (ES) cell technology. Using genomic DNA containing a portion of the mPMS1 gene we constructed a vector that upon homologous recombination causes disruption of the chromosomal mPMS1 gene. Mouse ES cells from the 129 mouse strain were confirmed to contain a disrupted mPMS1 allele. The ES cells were injected into C57/BL6 host blastocysts to produce animals that were chimeric or a mixture of 129 and C57/BL6 cells. The incorporation of the ES cells was determined by the presence of patches of agouti coat coloring (indicative of ES cell contribution). All male chimeras were bred with C57/BL6 female mice.

Subsequently, twelve offspring (F₂) were born in which the agouti coat color was detected indicating the germline transmission of genetic material from the ES cells. Analysis of DNA extracted from the tail tips of the twelve offspring indicated that six of the animals were heterozygous (contained one wild-type and one mutant allele) for the mPMS1 mutation. Of the six heterozygous animals, three were female, (animals F₂ -8, F₂ -11 and F₂ -12) and three were males (F₂, F₂ -10 and F₂ -13). Four breeding pens were set up to obtain mice that were homozygous for mPMS1 mutation, and additional heterozygous mice. Breeding pen #1 which contained animals F₂ -11 and F₂ -10, yielded a total of thirteen mice in three litters, four of which have been genotyped. Breeding pen #2 (animals F₂ -8 and F₂ -13) gave twenty-two animals and three litters, three of which have been genotyped. Of the seven animals genotyped, three homozygous female animals have been identified. One animal died at six weeks of age from unknown causes. The remaining homozygous females are alive and healthy at twelve weeks of age. The results indicate that mPMS1 homozygous defective mice are viable.

Breeding pens #3 and #4 were used to backcross the mPMS1 mutation into the C57/BL6 background. Breeding pen #3 (animal F₂ -12 crossed to a C57/BL6 mouse) produced twenty-one animals in two litters, nine of which have been genotyped. Breeding pen #4 (animal F₂ -6 crossed with a C57/BL6 mouse) gave eight mice. In addition, the original male chimera (breeding pen #5) has produced thirty-one additional offspring.

To genotype the animals, a series of PCR primers have been developed that are used to identify mutant and wild-type mPMS1 genes. They are: (SEQ. ID NOS: 139-144, respectively)

Primer 1: 5'TTCGGTGACAGATTTGTAAATG-3'

Primer 2: 5'TTTACGGAGCCCTGGC-3'

Primer 3: 5'TCACCATAAAAATAGTTTCCCG-3'

Primer 4: 5'TCCTGGATCATATTTTCTGAGC-3'

Primer 5: 5'TTTCAGGTATGTCCTGTTACCC-3'

Primer 6: 5'TGAGGCAGCTTTTAAGAAACTC-3'

Primers 1+2 (5'targeted)

Primers 1+3 (5'untargeted)

Primers 4+5 (3'targeted)

Primers 4+6 (3'untargeted)

The mice we have developed provide an animal model system for studying the consequences of defects in DNA mismatch repair and resultant HNPCC. The long term survival of mice homozygous and heterozygous for the mPMS1 mutation and the types and timing of tumors in these mice will be determined. The mice will be screened daily for any indication of cancer onset as indicated by a hunched appearance in combination with deterioration in coat condition. These mice carrying mPMS1 mutation will be used to test the effects of other factors, environmental and genetic, on tumor formation. For example, the effect of diet on colon and other type of tumors can be compared for normal mice versus those carrying mPMS1 mutation either in the heterozygous or homozygous genotype. In addition, the mPMS1 mutation can be put into different genetic backgrounds to learn about interactions between genes of the mismatch repair pathway and other genes involved in human cancer, for example, p53. Mice carrying mPMS1 mutations will also be useful for testing the efficacy of somatic gene therapy on the cancers that arise in mice, for example, the expected colon cancers. Further, isogenic fibroblast cell lines from the homozygous and heterozygous mPMS1 mice can be established for use in various cellular studies, including the determination of spontaneous mutation rates.

We are currently constructing a vector for disrupting the mouse mMLH1 gene to derive mice carrying mutation in mMLH1. We will compare mice carrying defects in mPMS1 to mice carrying defects in mMLH1. In addition, we will construct mice that carry mutations in both genes to see whether there is a synergistic effect of having mutations in two HNPCC genes. Other studies on the mMLH1 mutant mice will be as described above for the mPMS1 mutant mice.
